Ubiquinone vs. Ubiquinol: Which Type of CoQ10 is Better?

What’s the difference between ubiquinol and ubiquinone?

Both ubiquinol and ubiquinone are true forms of CoQ10, and the terms are often used interchangeably. From a chemistry standpoint, ubiquinol is the reduced form of CoQ10, whereas ubiquinone is the oxidized form.

Ubiquinol and ubiquinone: is one better than the other?

Research has not proven one form of CoQ10 better than the other, and given the body naturally converts between the two forms, it is unlikely that there is a big difference between them.

Which form of CoQ10 is more bioavailable?

The bioavailability of a supplement is the proportion which reaches systemic circulation and can be used by the body. Both ubiquinone and ubiquinol have high bioavailability.
